Does on-site CO₂ liquefaction at the Point of Origin or RED-certified Processing Unit require certification?

On-site CO₂ liquefaction at the Point of Origin or RED-certified Processing Unit does not require certification under the proposed ISCC approach, where the CO₂ is generated and liquefied at the same Point of Origin or RED-certified Processing Unit before entering the downstream certified supply chain.

The liquefaction activity, quantities, losses and GHG emissions must still be documented and verified. The Point of Origin or RED-certified Processing Unit may then forward the liquefied CO₂ with the applicable self-declaration or Sustainability Declaration, respectively.
